  1. Re: Can someone identify: MMJ patch panel?

    It used to be connected to three Digital DSRVB-AB DecServer 200 MC terminal
    servers. The eight D25 RS232 ports per DS200 were connected with octopus
    cables, concentrating eight D25 connectors to one Centronics style
    connector. If I dig deep enough in the cable-snake pit at work, I probably
    still have some of these cables.

    I have a VAX4000-200 with two "M3119-YA 8 LINE ASYNC COMMS CXY08"
    boards. Each have two of those 50-pins Centronics plugs, just like the
    SCSI plugs.

    Does anyone have the pinout for these plugs, so I can build my own
    serial fanout cable?
